Answer:
9.5 ft^2
Step-by-step explanation:
It’s just 4.75 * 2
The angle of a tangent and a radius is a right angle.
The missing length would be the hypotenuse. Use the Pythagorean theorem to solve.
X = SQRT(12^2 + 16^2)
X = SQRT(144 + 256)
x = SQRT(400)
X = 20
120+ 4(square root)15
120+15.49=135.49
135.49 is the perimeter
